铬钼钢以其优秀的强度、抗氧化性及耐腐蚀性广泛的应用于许多重要场所。但铬钼钢本身淬硬倾向大,属裂纹敏感性钢材,焊后容易产生裂纹。在此简要的分析导致焊接裂纹产生的因素,并针对性的提出相应的质量控制措施,以防止焊接裂纹的产生,保证焊接质量。 Chrome-molybdenum steel is widely used in many important places for its excellent strength, oxidation resistance and corrosion resistance. However, chromium-molybdenum steel tends to harden itself, is a crack-sensitive steel, easy to crack after welding. In this brief analysis of the factors that lead to welding cracks, and pointedly put forward the appropriate quality control measures to prevent the generation of welding cracks, to ensure the welding quality.
